I don't think MinGW can support %z even today, because the CRT DLL
doesn't.  See my other message.

That's true, but the main issue here is the library, not the compiler.

MinGW runtime does not replace the format conversion engine, it uses
the MS provided one, AFAIK.  It does augment the MS runtime with
several functions of the printf family, but AFAIK they do not include
replacement of the format-conversion code.  If you know otherwise,
please tell which MinGW source file includes this replacement.
